ASCII codeWe know that inside the computer, all the information is ultimately represented as a binary string. Each bits (bit) has 0 and 12 states, so eight bits can combine 256 states, which is called a byte. In other words, a byte can be used to represent 256 diff
/** read-only variables and constants const READ-only const int A;int const a;//are equivalent to the above line of code, all representing a constant shape number. int *const A;//const has a "left associative", that is, a const modifier *, then, it is not difficult to understand that the sentence represents a constant pointer to an integer, a pointer to an integer can be modified, but pointer a cannot be modified. The const int *a;//is equivalent to the following line, which, according to the "l
program that reads in an ASCII file thatLooksLike hex pairs, but then converts it to a true binary file with the corresponding bit patterns.
That is, it takes a file that looks like:
63 a0 de
And converts this ASCII file to a binary file that begins 0110 0011 (which is 63 in
The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard. The following is an
Files in a computer can be divided into two types: ASCII files and binary files.
An ASCII file is also called a text file. It is defined as a file containing ASCII characters. It is usually created by a text editor similar to NotePad. Similarly, binary files are defined as
What are binary files? What is ASCII? What is the difference between text files?
An ASCII file is also called a text file. When a file is stored on a disk, each character corresponds to one byte and is used to store the corresponding ASCII code.For example, the storage format of 5678 is 5 6 7 8.
Brief introductionThe Binascii module contains a number of binary representations that are used to convert binary and various ASCII encodings. These features are not typically used directly, but instead are encapsulated modules such as UU, Base64, or BinHex. The Binascii module contains faster, lower-level features written in C that are typically used by advanced
Binary to Text (ASCII) Conversiondescription:Write a function that takes in a binary string and returns the equivalent decoded text (the text is ASCII encoded).Each of the 8 bits on the binary string represent 1 character on the ASCII
Net: FTP is used to download files from the FTP server. It is found that some files have different sizes after being downloaded, which may be caused by ASCII transmission.
Check the differences between the two FTP transmission modes:
The difference between the ASCII mode and the binary mode is that the carriage return line breaks are processed, while the

From the file encoding methodFiles can be divided into ASCII files andBinaryTwo types of code files.
An ASCII file is also called a text file. When a file is stored on a disk, each character corresponds to one byte and is used to store the corresponding ASCII code. For example, the storage format of hundreds of thousands is:ASC: 00110101 00110110 00110111 00111
Requirements: Sometimes in the communication of some engineering, the receiving end receives the ASCII code (0101) is often the character information, this string of things stored in an int array (int a[7]), this time how to parse the corresponding character?Answer:#include #include int main (){//0 1 2 3 4 5 6int a[7]={0,0,0,0,1,1,0};"0" ASCII code, note the reverseint i; Loop variablePrint
Var a = '20140901 ';Alert (parseInt (a, 2); // convert 111 as a binary value. Ignore 60 (not binary) and convert from left to right only binary values.Alert (parseInt (a, 16); // convert allAccording to this method, it can be converted to any hexadecimalVar a = '20140901 ';Alert (parseInt (a, 10). toString (16); // convert a to a in hexadecimal notation, and then
var a= ' 11160 ';
Alert (parseint (a,2)); Converts 111 to 2, ignoring 60 (not conforming to binary), and converting from left to right only binary numbers are converted
Alert (parseint (a,16)); Convert all of them
In this way, it can actually be converted into any system
var a= ' 1110 ';
Alert (parseint (a,10). toString (16)); Converting a to 10 and then converting to 16 can also be a different system
